To. all. whom it concern:

Be it known that l, WALTERV A. SMITH, a

` citizen. Kof the United States, residing at California,` in the county of Harrison and State oi Iowa, have invented anew and useful Revetment, of which the following is a specifioatiorr- This irlrrontoii relatos to ravstmorits or riiatsv tor protesting levees and similar erribankments.

rlhe object of the invention is to provide a mat formed of a plurality ofl pivotallv-urlitsslA sectiens adapted tobe anchored to the banks Oi a stream, 'so as to protect the levee or embankment from the erosive action of the wat r. A

@I furtherobject of the invention is to generally improve this class of devices so. as to add tol their utility, durability, and. efficiency, as wellV as to reduce the cost of manufacture.V

these and other objects in view the'v invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, and illustrated in the accompanying drawings,y it being under-v stood that various changes in form, proportions, and minor details of construction may ba resorted to within tha soaps of the appended claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a per- Spective view showing the improved revetnient or protecting-mat in position on the banks of a stream. Fig. 2 is a vertical sectional vieW, and Fig. 3 is a front elevation of a portion of the mat. i

Similar numerals of reference indicate corresponding parts in all of the iigures of the rawings.

The improved mat is particularly designed for protecting the banks of rivers and similar streams from the detrimental action of flowing water and drift material and by way of illustration is shown anchored in position on the banks 5 of a stream 6.

The mat is preferably formed of a plurality i of upper andlower sections 7 andI 8 of any desired length and width, said sections being each formed of a series of spaced supporting poles or timbers 9, connected .by transverse barbed or smooth Wires l0, the latter bein nailed, stapled, or otherwise rigidly secured to one side of each pole, as shown. Secured to the opposite side of each pole are similar transverse barbed or smooth wires 11, and

interposed between the wires 10 and 11 is a ma of. tha trarialia'sf or! limbs 'of trees, oom- Stalks, brush, or tho. like, as'shovm The timbers l 9. Of V@ach mat-section are, 00,11.

heavy material 17 covered by an inner layer of straw or fiber and an outer layer brush, the opposite ends of the nanchor@coverings being tied or otherwise secured the ad1acent supporting-cable in any suitable ner, as by cords or wires 18'. l

' The Several appar and lower stations @Qm- Iirisiri tha mat ars Preferably 'iiiiitasl by suitab e tie-wires connecting the ends the adjacent poles or timbers,l soi that the of the anchors l7fWll Carisa aaah lower SIC- tori to automatically aooomriiedat itself' to the bad of tha stream, and. oo iisaqusntly tirvent the water `cutting under. said 'sections and destroying the levee or embankment. Disposed substantially parallel the timbers 9` are anchoring-'cables 20 one end of each of which is secured tothe trans- Vsrsa sables 12 and 1.3, While tha 'opposite ends' ef the cables are fastened,V in any suitable marmer to Pags' .or stakes 21, drrari iiito the banks of the stream, .as shown! In Constructing the mattlia Wires 10. al?? irst secured lto the timbers and tliebrushor branches placed in position on said wires, the Wires 11 eing subsequently extended over the top of the brush or branches and secured to said timbers'by nails, staples, or similar fastening devices. The vertical stay-wires Wires 10 and 11 and fastened in any suitable after which the diagonal stay-wires 15 are secured to the ends of timbers and the sinkers or anchors 16 placed in position on the lower cable 13, thus producing a strong durable mat which Will efectually resist the action of the Water and prevent the latter from washing away or disintegrating the banks of the stream.

Suitable sacks of sand or pieces of rock 21 i layer of fibrous material, preferably consist and 13, and secured to said supportingfeables ling arid strengthening the several matsaof 14 are then threaded over and under the stay- IOO manner to the supporting-cables 12 and 13,

lIO

ple, inexpensive, and elhcient device admirably adapted for the attainment of the ends in view.

' Having thus described the invention, what is claimed is- I l. A mat formed of a plurality of pivotally-united sections each comprising spaced timbers connected by transverse cables, tie members secured to the opposite sides of the timbers, fibrous material interposed between the tie members, and diagonal stay members connecting the timbers and engaging the tie members.

2. A mat formed of a plurality of pivotally-united sections each comprising spaced timbers connected by transverse cables, tie members secured to the opposite sides of the timbers and disposed in spaced relation, :fibrous material interposed between said members, vertical members alternately engaging the tie members and diagonal stay members connecting the timbers.

3. A mat formed of a plurality of pivotally-united sections each comprising spaced supporting-timbers, cables connecting said timbers, transverse tie members secured to the o posite sides of the timbers, fibrous materia interposed between the tie members, and anchors secured to one of the supporting-cables.

4. A mat formed of a plurality of pivotally-united sections each comprising spaced timbers, supporting-cables connecting the timbers, tie members secured to the o posite sides of thev timbers, fibrous materia intertimbers, supporting-cables connecting saidi,

timbers, tie-wires secured to the opposite Y.sides of the timbers, brush interposed between the tie-wires, vertical stay-wires engaging alternate tie-wires, anchors secured to the timbers, diagonal braces connecting said timbers and engaging the tie-wires, and anchoring-cables connected to the supportingcables.

6. A mat formed of a plurality of pivotally-united sections each comprising spaced timbers, supporting-cables connecting the timbers, tie members secured to the o posite sides of the timbers, fibrous material) interposed between the tie members, anchors secured to one of the supporting-cables, a layer of fibrous material covering the anchors and ,secured thereto by binding-wires, and anchoring-cables secured to the -supportingcable.

7. A mat formed of up er and lower sections pivotally united an each comprising spaced timbers, connected by transverse supporting-cables, stay-wires secured to the oposite sides of 'the timbers, brush interposed etween the stay-wires, vertical wires engaging alternate tie-wires and secured to the supporting-cables, diagonal braces connecting the timbers, anchors secured to one of the supporting-cables of the lowersections, anchors carried by the timbers, and anchoringcables serving to connect the upper and lower sections of the mat.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
